N2 - To achieve carbon neutrality in response to climate change, the Japanese government declared to reduce CO2 emissions in 2030 by 46% from 2013. Therefore, there is an urgent need to reduce CO2 emissions in the building sector further, accounting for about 1/3 of Japan's total CO2 emissions. This study aims to study the possibility of carbon-neutral districts in Tokyo 2050, by using 3D CityGML. We focus on CO2 emissions and reductions from buildings and simulated solar radiation on the exterior walls or roof surfaces obtained from the 3D CityGML Model, PLATEAU. Photovoltaic power was calculated based on the results of the solar radiation calculation and building CO2 reduction by renewable energy was estimated. From the simulation results, it was found that wall-mounted PV also contributes to some reductions of building CO2 emissions during operation as well as roof-mounted PV.
